Since it has become the requirement of outboard motor operators that themotors exhaust 20 under water, it has become necessary to run an exhaustpipe parallel with the drive shaft housing and spaced therefrom. Suchconstruction makes it impossible to mount the motor so that the same mayswing throughouta complete revo.- 25 lution where rotationis had aboutthe axis of the drive shaft housing and thus be used for propulsion ineither direction. The present invention provides a construction wherebya motor of such characteristics may be mounted so as to make a completerevolution whereby the desired advantages may be procured.

For the purpose of illustrating the application of my invention I haveshown in Figs. 1 and 2 a portion of a boat l0. Inasmuch. as theinvention does not lie in the boat only a portion of the boat has beenillustrated. The part of the boat illustrated consists of a transom Ilto which is attached a keel l2. A knee I3 is disposed between thetransom and keel. The boat also in- 40 cludes a plankng I4 which isattached to the transom il and which forms the sides of the boattogether with plankng l5 which is attached to the lowermost portion ofthe transom Il and to the plankng I4 to form the bottom of theyboat. 45A seat i6 carried on stringers i1 is provided at the rear end of theboat.

The outboard motor used with my invention may be of any of theconventional types such as are now in common use and Asince theinvention does not reside in the specic construction of the motorproper, the same has only been generally illustrated. The outboard motoris indicated by the reference numeral 2l and consists of a power 55table 35.

unit 22 including one or more cylinders and pistons and correspondingconnecting rods operated thereby but-not shown. The connecting rods ofthe motor are connected to a crank shaft not illustrated which may bedirectly connected to a. drive shaft-23 or which may be integraltherewith. The shaft 23 is mounted for rotation with- /in a drive shafthousing 24 which is tubular in form and which is attached at its upperend to the power unit 22. The lower end of the housing 24 has secured toit a gear housing 25. Within this housing are bevel gears, not shown,one of which is driven by drive shaft-23 and the other which drives thepropeller shaft 26. Shaft 26 has secured to it a propeller 21. vTheupper end of the crank shaft or the shaft 23 as the case may be hassecured to it a. y wheel 28. A fuel tank 29 extends about the ily wheel.Attached to the power unit 22 is a steering lever 30 which has mountedon the end of it a handle 3| by means of which the entire outboard motormay be` rotated to steer and reverse the direction of propulsion of theboat as will presently become apparent.

The exhaust from the power unit 22 is carried through an exhaust pipe 36which is connected at its upper end with the exhaust ports of theoutboard motor and which is attached to its lower end to a muilier 31carriedby gear housing 25 and adapted to discharge below the waterlevel. In the housing 25 is provided a pump 38 by meansof which water ispumped through a pipe 39 and into the Water jackets of the cylinders ofthe power unit 22 and subsequently discharged therefrom. The two pipes36 and 39 lie parallel with the drive shaft housing 24 and disposed ineccentric relation thereto'and spaced therefrom.

My invention comprises aclamp 32 to which is attached a mounting 33.Mounting 33 carries a bracket 34 which rotatably supports a turn Thedrive shaft housing 24, the exhaust pipe 36 and water pipe 39 all passthrough the turn table 35 and the entire outboard motor is supported onthis turn table. 'I'hese various parts will now be described in detail.

The clamp 32 is C-shaped in form, being constructed with spaced verticallegs 4| and 42 and a connecting portion 43 therebetween. These portionsare T-shaped in cross section and have flanges 44 and webs 45 extendingoutwardly therefrom. 'I'.he flange 44 of the leg 42 is adapted to restagainst the rear surface of the upper portion of the transom of the boatI0. 'I'he lowermost portion of the leg 4| is formed with a boss 49 whichis threaded to receive an adjusti`ng screw 5|. This screw carries aswivelly attached head 42 which is adapted to engage against the innersurface of the transom and when the said screw is rotated by means ofhandle 53 the clamp is urged into engagement with the transom. Theflange 44 of leg 42 is of considerable width so that a sufficientbearing surface is provided to securely attach the clamp to the boat.

The mounting 33 is anguular in form and is constructed with two legs 54and 55. The leg 54 is arranged horizontallywhile the leg 55 is arrangedvertically and depends` from one end of the leg 54. Bothof these legsare U-shaped in cross sections being constructed with flanges 56 and aweb 51 therebetween. The mounting 33 is disposed so that-the flanges 56thereof straddle the web 45 of the leg 4| of clamp 32. 'I'h'e mounting33 is pivoted to the clamp 32 by means of a bolt 58 which extendsjointly through the two va ball 16 which is recesses 83 and 84 flanges56 of the mounting 33 and the web 45 of the said leg of clamp 32. Thisbolt is disposed at the free end of the leg 54 of mounting 33 so thatwhen the said mounting is swung about the bolt 58 as a pivot the angularposition of the mounting is varied with respect to the boat.

At the lower end of is provided a boss 59 the leg 55 of mounting 33which is threaded to receive a screw 6|. This screw engages the web 45of the leg 42 of clamp 32 and serves to shift the angular position ofthe mounting. A handle 62 carried by this screw permits of readilyadjusting the same.

Issuing outwardly from the leg 55 of mounting 33 is a bracket 63. 'I'hisbracket is in the shape of a plate and is constructed annular in formbeing provided with a circular opening 64 extending completely throughthe same. By 'means of this opening two annular shoulders 65 and 66 areformed on the said bracket 63 which are at right angles to the axis ofthe opening 64 and which form a track extending circularly about thesaid opening. The bracket 63 is attached to the leg 55 at a localityabove the screw 6| so as not to interfere with the operation thereof.

Rotatably mounted on the track formed by the shoulders 65 and 66 is aturn table 61 which comprises a disc 68 rotatably mounted within thecircular opening 64. This disc is constructed with a ange 69 extendingoutwardly therefrom and which rests upon the shoulder 65. The disc 68 isof such thickness that the lowermost surface 1| thereof lies flush withthe shoulder 66. Attached to the disc 68 is a plate 12 which is ofsubstantially the same size as the flange 69 of said disc and whichengages the lowermost shoulder 66 of the bracket 63. 'I'he plate 12 isattached to the disc 68 by means of screws 13 which extend through thesaid disc and are threaded into the plate. It will readily becomprehended that the turn table 61 becomes rotatably mounted formovement along the track of the bracket 63 and may make a completerevolution with respect thereto.

For the purpose of arresting the turn table 61 in certain positions thefollowing construction is employed. Formed in the bracket 63 is a bore18. A screw 15 is threaded into the outer end o-f this bore. Within thisbore is mounted urged into engagement with a number of sockets 11 in thedisc 68. A compression coil spring 14 seated at one end against the ball16 and at its other end against the screw 15 holds the ball in operativeposition. The sockets 11 are of such shape that the turn table 61 isheld in proper position but may be released upon the exercise ofsufficient force to the handle 3|.

The outboard motor of the invention is carried by the turn table 61 andis attached thereto in the following manner: 'Formed in the disc 68 andin the plate 12 is `an opening 8| of such dimensions as to snuglyreceive the drive shaft housing 24, the exhaust pipe 36 and the waterpipe 39. In the particular type of outboard motor shown, the air intake82 of the motor extended to a position in proximity to the localitywhere' it was desired to attach the turn table to the motor. Toaccommodate this intake, the opening 8| was constructed accordingly asshown in Fig. 3. The opening 8| is formed with two in which the housing24 and the pipe 36 t; Sleeves 81 and 88 mounted upon the housing 2l andthe pipe 36 engage the power unit 22 and support the entire structurethrough the disc 68. Two collars 89 and 9|. provided with set screws 92,are mounted on the housing 24 and pipe 36 and engage the under side ofthe plate 12 and hold the parts rigidly attached to the turn table 61.

In assembling the motor on the support the gear case 25 is removedwhereupon the sleeves 81 and 88 may be assembled upon the housing 24 andpipe 36. Thereafter the parts may be inserted in the proper positionwithin the hole 8| of.disc 68 and plate 12 and the collars 89 and 9|applied to said housing and pipe. After these collars are secured inplace .through the set screws 92 the gear case 25 is again applied andthe outboard motor is ready for use.

The use of my invention is as follows: After the clamp 32 has beenapplied, screw 6| is used for adjusting the angularity of the propeller21 with respect to the surface of the water. The outboard motor is thensteered in the customary manner through the' handle 3| by rotating theentire motor through the turn table 61 and the track formed in themounting 33. Whenever it becomes desired to reverse the travel of theboat the entire outboard motor is completely turned around through anangle of 180 degrees until the same occupies the position shown .in Fig.2. This may b e accomplished without stopping the motor. When it isdesired to run the motor continuously, in a directly forward direction,the motor is shifted until the ball 16 engages the proper socket 11which affords suiiicient frictions to maintain the motor in the desiredadjusted position.

The advantages of my invention are manifest. An extremely simple andpractical construction is provided wherebyvan outboard motor having anunder water exhaust may be turned throughout a complete revolution sothat the motor may be used to propel the boat either in a forward orrearward direction without reversing the motor. My device operates in anexceedingly effective manner. My invention can'be used with varioustypes of outboard motors and without reconstruction thereof. With myinvention adjustment of the angularity of the propeller with respect tothe surface of the water can readily be made while the motor is inoperation.

Changes in the specific form of my invention, as herein disclosed, maybe made within the scope of what is claimed without departing from thespirit of my invention.
